A. Class X has a greater proportion of boys than Class Y

Step-by-step explanation:

- Before choosing any objective, first relate the two proportions.

Multiply class Y by 2:

[tex]{ \rm{y = 2(4 : 5)}} \\ { \rm{y= 8:10}}[/tex]

- So it can be related with class X as the ratios have a common proportion of girls; 10

[tex]{ \rm{x= 9:{ \green{10}}}} \\ { \rm{y = 8:{ \green{10}}}}[/tex]

- By observation, we see that class X has a greater number of boys than in class Y

The given percentage cannot be represented on the grid.

What is percentage?

A percentage (from Latin: per centum, "by a hundred") is a quantity or ratio stated as a fraction of 100 in mathematics. The percent symbol, "%," is commonly used, however the abbreviations "pct.", "pct," and sometimes "pc" are also used. A % is a non - dimensional (pure) quantity; it does not have a unit of measurement. In the context of sports statistics, the term "%" is frequently used incorrectly since the referred figure is stated as a decimal proportion, not a percentage. Similarly, a team's winning percentage, or the fraction of matches won, is commonly reported as a decimal proportion; a team with a.500 winning percentage has won 50% of its matches.

Based on the weight of the plastic to the weight of the paper, the ratio of plastic to paper in the simplest form is 6 : 1

To find the ratio of plastic to paper, there is a need to convert the weights such that they have the same units.

Assuming we convert the plastics to grams, the number of grams of plastic would be:

= 3 kg x 1,000 grams per kg

= 3,000 grams

The ratio then would be:

3,000 grams of plastic   : 500 grams of paper

To get to the simplest form, divide both sides by 500:

Answer:

2x=108

Step-by-step explanation: This is the equation because when it says twice a number, you are multiplying a number two times. In this case, the number is not given, so x is the variable being multiplied two times. If the number was 8, it would look like this: 2(8)=108. Of course this isn't true, but to find the actual answer you would divide two on both sides of the equation. This is so that both of the two's cancel out on the left side of the equation. and the variable is left on that side. Our goal is to isolate the variable. In these types of equations, our goal is to isolate the variable and find what the variable is worth. If we do 108 divided by 2 that gives us 54. Since there was x left on the left side of the equation and there is 108 left on the right side we have our equation. x=54

If there is no solution to a compound inequality, it can involve AND.

A sentence having two inequality statements connected by the words "or" or "and" is referred to as a compound inequality. The conjunction "and" denotes the equal validity of both statements in the compound sentence. The conjunction "or" means that the entire compound sentence is true as long as either of the two statements is true.

The term "OR" can help us find more solutions, whereas the phrase "AND" can help us find less solutions. As a result, we can create a compound inequality with no solution by using "AND."

Therefore, if there is no solution in compound inequality, it may involve AND.

A compound interest that pays 5% interest compounded daily is preferable. This is so even though the interest rates on the two accounts are equal, the 5% interest compounded daily account is used more frequently.

 Interest is the cost of borrowing money, such as the sum added to a loan debt. It is also possible to classify the rate paid for holding money on deposit, such as in the case of a certificate of deposit. The two ways to calculate interest are simple interest and compound interest.

On the principal, or original loan amount, of a loan, simple interest is calculated.

Since compound interest is calculated using both the principal and the accrued interest from previous periods, it is frequently referred to as "interest on interest".

If interest is computed on a compound basis rather than a simple basis, the amount of interest that must be paid on a loan can vary significantly. Positively speaking, the magic of compounding may be a powerful tool for wealth growth and can work in your favor when it comes to your assets.

Simple interest and compound interest are fundamental financial concepts, but understanding them thoroughly may enable you to make better choices when applying for a loan or making investments.

10 pounds of food each chicken eat last week.

This is a problem from an algebraic equation. We can solve this problem by following a few steps.

Each chicken eats the same amount of food, as per the question. Let's assume there is x number of chickens.

Therefore, if each chicken eats the same amount of food then the total food required for all chickens is, (x × x) = x² pound.

Again, Mrs. Rollins bought 100 pounds of chicken food.

Hence x² is equivalent to 100 pounds. We can generate an equation from this. Which is,

x² = 100

Or, √x² = √100         [ root both sides ]

Or, x = 10

Now, we can conclude that there are 10 chickens and each chicken eats 10 pounds of food in a week.

The number of minor damaged books in 73500 book collection is 8,673 books.

Given that, 661 books had no damage, 78 books had minor damage, and 26 books had major damage.

Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

Let the minor damaged books be x.

Now, 78 : 661 :: x : 73,500

⇒ 661x = 73500 × 78

⇒ 661x = 57,33,000

⇒ x = 57,33,000 ÷ 661

⇒ x = 8,673.22

Step-by-step explanation:

D is directly proportional to x. D=36 when x=5. Work out the value of D when x=8.

Because they are directly proportional:

x/D = x/D

5/36 = 8/D

multiply both sides by D:
D(5/36) = D(8/D)

5D/36 = 8

multiply both sides by 36:

36(5D/36) = 8 * 36

5D = 288

divide both sides by 5:

5D/5 = 288/5

D = 288/5

or D = 57.6

Answer:

y = 4x -80

Step-by-step explanation:

We need the slope and the y intercept.

The y intercept is -80.  This is where the line crosses the y axis.

The slope is the change in y over the change in x.  

Let's go from point (0,-80) the y intercept the the point that cross the x axis (20,0)  Start at -80, how many units to you go up until you are at the same level as point (20,0)? 80 units.  Now, from (0,0) how many units do you go right to get to (20,0)? 20.

We end up go 80 unit up and 20 units right, this would be written [tex]\frac{80}{20}[/tex] Which simplifies to 4.  This is our slope.

Slope (m) = 4

y intercept (b)= -80  Plug those into

y = mx + b

y = 4x -80

The quadratic function that models the path of the second kick is given by:

y = -2/125(x - 25)² + 10.

The equation of a quadratic function, of vertex (h,k), is given by the following rule:

y = a(x - h)² + k

In which the coefficients are explained as follows:

For the first kick, the equation is:

y = -1/40(x - 25)² + 15.

Meaning that the ball reached a maximum height of yards after an horizontal distance of 25 yards.

For the second kick, the horizontal distance is the same, but the maximum height if 5 yards less, that is, of 10 yards, hence the vertex is:

(h,k) = (25, 10).

Hence the equation is:

y = a(x - 25)² + 10.

After 50 yards, the ball hits the ground, hence the leading coefficient a is found as follows:

0 = a(50 - 25)² + 10

625a = -10

a = -10/625

a = -2/125

Hence:

y = -2/125(x - 25)² + 10.

The equation of the line parallel to 3x-6y=3 and passes through (-2, 3) is y = 1 / 2 x + 4

The equation of the line passes through (-2, 3) and it is parallel to the equation 3x - 6y = 3.

Therefore, the equation of a line can be represented as follows:

y = mx + b

where

Parallel lines have the same slope.

Hence,

3x - 6y = 3

3x - 3 = 6y

y = 1 / 2 x - 1 / 2

Therefore, the slope of the equation is 1 / 2.

Let's find the y-intercept using (-2, 3).
